Unless you have a locker, you might want two straps and two short boards. :thumb:
You would also need to test wheel well clearance to make sure it doesn't hit anywhere AND be very careful to not mount the board too far to the inside where it might grab something else in the wheel well.
It's a good idea if you're really really stuck, but there's a lot to go wrong there. I wouldn't risk it unless absolutely necessary. I also feel like he's in a 2WD ram on street tires...
